Urinary Tract Calculi V: Nursing Management

238
AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

337
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urinary Tract Calculi I: Introduction

364
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Urinary Tract Calculi III: Medical Management

154
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Acute Pyelonephritis II: Diagnostic Studies and Management

249
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Summary

A symptomatic ureteral stump after nephrectomy can cause ureteritis due to stones. Prompt distal ureterectomy is recommended to prevent further complications.

Area of Science:

  • Urology
  • Surgical Pathology

Background:

  • A 52-year-old male presented with fever and right lower abdominal pain 22 years post-right nephrectomy.
  • The patient had a history of a nonfunctioning right kidney necessitating nephrectomy.

Observation:

  • Surgical exploration revealed a symptomatic right ureteral stump.
  • The ureteral stump was surgically removed en bloc.

Findings:

  • Pathological examination confirmed acute and chronic ureteritis.
  • The ureteritis was attributed to a ureteral stone, with no evidence of malignancy.

Implications:

  • Symptomatic ureteral stumps, though rare, can lead to significant complications like ureteritis.
  • Early distal ureterectomy is advised for symptomatic ureteral remnants to avoid sequelae.
  • This case highlights the importance of considering ureteral stump pathology in patients with prior nephrectomy and recurrent abdominal pain.
